Or even, what if they accidently changed the timeline for their better, but someone else came by and told them it needed to change back? Do the story from the opposite perspective, with the other guy winning and changing the timeline, and just don't even try to explain it in Atlantis, just one week, all of a sudden everything is ever so slightly different.
You know what you just described? That DS9 Episode... Children of Time or whatever it was called, where "future" Odo stops the Defiant from crashing, saving Kira but "killing" all of the unborn children.
As a reset time travel episode, I think at the very least it had more of an impact that this one.
